Cataracts are the clouding of the lens, which is the lens to see far and near. With age, the lens loses its transparency and becomes increasingly more rigid.
Cataracts affect mainly people over 60 years. However, it is important to note that there is a rare form of congenital cataracts, ie children at birth have opacities in the lens that prevent them from seeing.
Symptoms of cataracts
In the early stages of cataracts, people detected difficulty reading, what is known as farsightedness or presbyopia. Progresses changes in lens transparency, the person begins to notice besides the decrease in near vision problems to see from afar. That is when it comes to cataracts.
The first symptoms are dazzling and decreased vision, especially in close view. Patients often also complain of tearing and feeling of eyestrain.
With progressive clouding of the lens, the patient usually refer significant decrease in vision with misty feeling.
Causes of cataracts
Specialists in Ophthalmology claim that the cause of the falls remains uncertain. It is a process that occurs in patients from 50 years, so age is the best known factor, although not the only, otherwise all people should be operated.
Currently, the treatment of cataract surgery remains. Operating only you can correct the symptoms they produce and restore vision
The surgical technique is phacoemulsification with intraocular lens implantation to compensate for the lens. Until relatively recently, they could only use lenses that corrected distance vision or near. At present there are multifocal lenses that can recover the vision of far and near. With these advances, cataract surgery attempts to restore vision function of young healthy eye.
